Which of the following is the correct quadratic form of Ostwald's dilution law equation for an $AB$ type electrolyte?

The molar conductivity of $0.01 \ M$ acetic acid at $25^{\circ} C$ is $16.5 \ \Omega^{-1} \ cm^2 \ mol^{-1}$ and its molar conductivity at infinite dilution is $390.7 \ \Omega^{-1} \ cm^2 \ mol^{-1}$. What is its degree of dissociation?

The equivalent conductance of benzoic acid is $12.8 \ ohm^{-1} \ cm^{2} \ eq^{-1}$. If the equivalent conductance of benzoate ion and $H^{+}$ ion at infinite dilution is $42 \ ohm^{-1} \ cm^{2} \ eq^{-1}$ and $288.42 \ ohm^{-1} \ cm^{2} \ eq^{-1}$ respectively,then its degree of dissociation is ............. $\%$
